Kazuki's red aura sputtered, barely holding shape against the overwhelming gravitational pressure of Kairyuuha’s Dimensional Vortex.

  But then—it happened.

  A rupture.

  Kazuki’s trembling fingers twitched. In a final act of defiance, he channeled all of his leaking mana into the surrounding vortex gates. Turbulences began to form inside Kairyuuha’s domain. Tiny, chaotic anomalies that pushed the boundaries of equilibrium.

  > “You truly are incredible,”* Kazuki whispered through clenched teeth, his body barely upright. “To keep mana this stable under such strain... you’ve mastered more than I could’ve imagined.”

  Kairyuuha remained silent, gaze fixed, observing.

  But Kazuki’s own Forecast domain was faltering, edges crumbling under the rotational pull of Kairyuuha’s violet sphere. The red box began to fracture, fragments of geometric magic floating away.

  Then—impact.

  Kairyuuha’s domain engulfed him, consuming Kazuki’s weakened Forecast.

  He vanished.

  But not before—he summoned one final turbulence.

  A jagged tear in the fabric of space and mana.

  Then came the light.

  A blinding, celestial explosion—brighter than any star—erupted at the site of the collapse. The entire battlefield froze, even distant armies locked in battle paused to gaze at the blinding supernova of pure mana detonation.

  The Vortex imploded, spinning into itself like a dying star collapsing under its own gravity.

  Kairyuuha and Kazuki were thrown apart, only to stabilize again.

  ---

  The second phase began.

  Kazuki, bloodied but upright, his body cracking with red aura and divine tremors, reshaped his domain mid-air. A new Forecast emerged—more jagged, unpredictable, shaped not as a box now, but like a fragmented prism. It reflected realities, each mirror slicing into Kairyuuha’s vortex.

  Kairyuuha, smiling faintly, summoned another domain—his aura now deeper, more sinister. A violet web twisted into formation, this one slowly rotating in layers, unfolding like a flower opening in reverse.

  The battle wasn’t just of strength. It was of form, rhythm, and dimensional tempo.

  > Kazuki manipulated turbulence and mirror-logic to overwrite Kairyuuha’s inputs.

  >

  > Kairyuuha used radius control and pulse wave harmonics to nullify interruptions before they destabilized.

  And for the first time—Kazuki gained the edge.

  > “I can do it...” Kazuki thought. *“I can rewrite him. My forecast can outpredict even his vortex.”

  He lunged—beginning the final strike.

  ---

  But Kairyuuha moved faster.

  A third domain unfurled.

  Dimensional Vortex: Chambers of a Willess Prison.

  The moment it activated, Kazuki froze.

  He gasped, not because of pain—but because he couldn’t feel his own mana.

  > “I... can’t move.”

  Chains—black and gravitational, formed of crushing pressure and logicless resistance—snapped around his limbs. The domain didn’t overwrite, it removed his ability to cast.

  Kazuki’s aura flickered, and the red glow dimmed.

  > “What is this?!”

  Kairyuuha walked slowly toward him, no longer floating but stepping across folded dimensions. He extended a single hand.

  Energy surged—not outward, but inward.

  From Kazuki... to him.

  A pulse echoed through the stars.

  Kazuki’s mind shattered for a moment. The world stopped.

  And he collapsed.

  ---

  The domain vanished like it had never existed.

  Kairyuuha stood in the void, then pointed downward.

  Kazuki's body, lifeless and silent, was now lying on the battlefield below.

  When the armies looked down—the strongest hero of the new age lay broken, unconscious, unmoving.

  Even the wind stopped.

  The world trembled.
